Abstract
L'invention concerne un procédé, une unité de commande et un système permettant de commander les transferts dans un système de radiocommunication au moyen d'un système de zone continue. Un transfert progressif (soft handoff) est possible entre les membres d'une zone continue particulière mais non entre les membres de zones continues différentes. Le transfert par transmission successive (hard handoff) est possible entre les membres de zones continues différentes mais non entre membres de la même zone continue.
